CRS-8 Tsvangirai was detained by police several times during the runoff campaign, and on two occasions has sought refuge in the Dutch Embassy. The MDC's Secretary General, Tendai Biti, was arrested in June 2008 upon return from South Africa and has been charged with treason. After two weeks in jail, he was been released on bail. On June 13, former U.N. Secretary-General Kofi Annan joined over 40 African leaders and former heads of state, including the group known as the Elders, in a letter calling on the government to stop the violence, postpone the runoff, and ensure conditions for free and fair elections. On June 22, less than a week before the runoff, ZANU-PF supporters, armed with sticks, iron bars, and rocks, blocked an MDC rally in Harare. Citing the high number of attacks against MDC supporters and the lack of a level playing field, Tsvangirai withdrew from the race the following day.

They also noted the "disruption of campaigning of the opposition party and the regrettable inaction of the law enforcement agencies," and cited harassment of their own observers. The SADC mission found that the pre-election period did not conform to SADC Principles and Guidelines Governing Democratic Elections, which impinged on the credibility of the electoral process. Ultimately, the delegation reported that runoff "did not represent the will of the people of Zimbabwe."34 The observer delegation from the Pan-African Parliament (PAP) was similarly critical of the runoff, saying, "political tolerance in Zimbabwe has deteriorated to the lowest ebb in recent history." The delegation reported witnessing roadblocks and "male-dominated groups [that] intercepted voters and gave them pieces of paper on which they were required to write the serial number of their ballots" at many polling stations. The PAP's report questioned the impartiality of the ZEC, and found that "the current atmosphere prevailing in the country did not give rise to the conduct of 33 (...continued) June 17, 2008. 34 Preliminary Statement Presented by the Hon.
